Straight seam welded pipes are steel pipes made by welding hot-rolled or cold-rolled steel plates or steel strip coils on welding equipment.

The production process of straight seam welded pipes is much simpler compared to spiral steel pipes, and it is mainly divided into two types: high-frequency welded straight seam steel pipe and submerged arc welded straight seam steel pipe.

The characteristics of straight seam welded pipes include high production efficiency, low cost, and rapid development speed. These pipes are mainly used for small diameter welded pipes, and they find applications in various industries such as water supply engineering, petrochemical industry, chemical industry, electric power industry, agricultural irrigation, and urban construction.

The uses of straight seam welded steel pipes include water supply and drainage, gas transportation, and structural applications such as pile driving pipes, bridges, wharfs, roads, and building structure pipes
